Lin Tianyi was once the Sword Sovereign of the Nine Heavens. At his peak, he forged the Voidheart Scripture, a technique feared by gods and demons alike. Hunted by the sects he protected, he was ambushed and his soul shattered. Reborn centuries later, his soul awakens in the frail body of a discarded outer disciple named Lin Chen. Stripped of power, status, and mocked for his "useless" spiritual root, he inherits the boy’s burning grudge against a noble house. Bound by karma and too weak to fight, how can he climb from the dirt, reclaim his sword, and make the entire cultivation world bow once more?!
